AST SpaceMobile and our global partners are building the first and only space-based cellular broadband network to be accessible by standard smartphones. Called SpaceMobile, this ultra-powerful network is being designed to provide connectivity at 4G/5G speeds everywhere on the planet – on land, at sea and in flight. Position Overview We are seeking a RAN Wireless NOC Engineer to monitor, triage, and ensure the stability of satellite connectivity across signaling, routing, SIM provisioning, OSS integrations, and core-network interactions. This role handles alarms, validates routing behavior, diagnoses signaling and gateway/core issues, and coordinates closely with partner NOCs to maintain high availability across commercial and beta-grade connectivity flows. By diagnosing faults, validating service paths, and responding to alarms across commercial and beta services, this role ensures compliant service flows and minimizes customer-impacting disruptions, playing a critical role in 24/7 operational continuity and rapid incident response.
Responsibilities:
•
Monitor signaling pathways, routing behavior, SIM flows, OSS hooks, and cross-core interactions impacting satellite service.
•
Detect, acknowledge, and triage alarms from monitoring platforms, ensuring rapid response and detailed logging.
•
Escalate anomalies based on severity, impact, and operational thresholds.
•
Validate routing tables, signaling transactions, and core-network behavior during faults or degradation events.
•
Diagnose issues across gateway, core, OSS, and cross-domain integrations affecting service connectivity.
•
Perform detailed event analysis, correlate logs, and support root-cause investigations with engineering teams.
•
Serve as the operational interface with partner NOCs across incident handling, alarm correlation, and workflow alignment.
•
Coordinate multi-party triage calls, share logs and findings, and ensure timely tracking and closure of partner-linked issues.
•
Maintain consistent communication loops and follow defined escalation paths.
•
Ensure signaling and routing flows remain compliant across commercial and beta-grade service classes.
•
Perform periodic checks on SIM provisioning paths, authentication flows, and connectivity stability.
•
Validate OSS integration points, alarms, KPIs, and data hooks supporting service assurance visibility.
Requirements:
•
Bachelor's degree in Telecommunications, Computer Science, Electronics, or a related technical field.
•
Experience:
•
2-5 years in NOC operations, telecom monitoring, satellite operations, or core-network support.
•
Experience working with signaling flows, routing tables, authentication paths, or mobile-core elements.
•
Hands-on exposure to multi-vendor NOC operations, incident workflows, and partner escalations.
•
Strong understanding of signaling (e.g., Diameter, SIP, NAS), routing fundamentals, and core-network behavior.
•
Knowledge of telecom connectivity flows (SIM activation, attach procedures, mobility, authentication).
•
Experience analyzing logs, traces, routing tables, and event correlations across network elements.
•
Familiarity with OSS/NMS tools, alarms, KPIs, dashboards, and monitoring platforms.
•
Hands-on experience with Linux, basic scripting (Python/Bash), and troubleshooting tools.
•
Certifications in networking (CCNA, CCNP, JNCIA, JNCIS) or telecom operations.
•
Basic understanding of satellite network components, gateways, or hybrid RAN-core flows.
